I've hard this same issue with Laravel Spark 6.0 today. To fix it, set you
APP_URL to a proper URL matching your site. Finally go into your database and change the
photo_url url to match your domain in the users table.
I hope that helps.

I had this issue also today. In my case I had installed php5.6 as one of my sites needed that. In the end i solved it by changing the php5.6 fpm process to run as forge instead of www-data
; Unix user/group of processes ; Note: The user is mandatory. If the group is not set, the default user's group ; will be used. user = forge group = forge
I had this issue also and I fixed it by opening up the "Oracle Virtual Box Manager" GUI and go to "Settings" -> "Network" and choose "Adapter 1" then expand the option by clicking on the arrow and make sure that "Cable Connected" is checked.
Hope that helps.
